Latest Patents

One of Rast's latest patents is the "Rocket Motor Exhaust Scrubber." This invention features a wet scrubber with a series of chambers designed to capture and cool exhaust gases generated during static test firings of rocket motors. The exhaust gas enters an inlet to the first chamber, where it is cooled and slowed by a spray solution. Hydrochloric acid (HCL) gas is condensed and absorbed by the spray solution, precipitating to a liquid slurry at the bottom of the device. The remaining exhaust products then enter a demister chamber, where nozzles continue to spray the gases as they pass upward through a mesh-style demister at the top of the vessel. This demister effectively filters liquid and solid waste particles from the gas stream, allowing clean, dry gases to be accelerated through a centrifugal fan into the atmosphere. Additionally, a deflector is positioned within the inlet to the first chamber to contain parts in the event of a motor malfunction.

Another notable patent is the "Miniscale Ballistic Motor Testing Method for Rocket Propellants." This method utilizes a miniscale ballistic test motor to determine burn rates over an operating pressure range, allowing for the testing of small propellant samples. The abbreviated procedure involves loading a small-scale test motor with the propellant sample, conditioning the test motor and sample, firing the propellant sample, and recording data.
